Spray Battery Could Revolutionize Energy Storage

A team of mechanical engineers from Rice University have invented revolutionary, spray-on rechargeable batteries that could be combined with solar cells to create self-sufficient, energy conversion-storage devices.

By breaking down the different components of a battery and rendering them into a liquid form, the technology could revolutionize widespread renewable energy capture, storage and utilization and the way devices are powered.

Moreover, a new and independent type of energy conversion-storage device could be created by fitting a series of these batteries grouped together to a series of solar cells. This energy storage device could then be used to convert any outdoor surface to an energy conversion-storage device.

The primary detraction of the spray-on battery technology is that lithium-ion batteries need oxygen-free, dry conditions to be created since they are made using toxic, flammable and corrosive materials. However, with further research to develop electrodes less sensitive to moisture and oxygen, as well as paints that could completely protect the spray-painted batteries from these elements, the engineers foresee the paints being used at a large scale in industrial environments.
